Astronomy
Geology
Environmental science
Explanation:
The study of the space around earth and the universe including meteoroids and galaxies that are trillion of miles away is called astronomy.
Astronomy has involves the study of everything in the universe. What started off as monitoring of star positions now uses sophisticated telescope and spacial probes to obtain information about the expanding universe.
Geology is a science that studies the earth rocky surface to determine when and how the earth formed and how its surface is constantly changing.
Our blue planets is a dynamic celestial body. Geology combines different disciplines like physics, biology, chemistry e.t.c to make meaning of the earth.
Environmental science is the study of complex interactions taking place between living organisms and earth's non-living systems.
It simply implies the interaction between living organisms and their environment.

Answer:
A pure substance is made up of only one ingredient or combination. A mixture is made up of two or maybe more separate components that are not chemically linked.
Explanation:
Answer:
4.955x10¹²nm
Explanation:
It is possible to obtain wavelength from the frequency of a wave using the expression:
ν = C / λ
Where wavelength, ν, is given in m
Speed of light, C, is 2.998x10⁸m/s
And frequency, λ, is given in Hz = s⁻¹ = 6.05x10⁴s⁻¹
ν = C / λ
ν = 2.998x10⁸m/s / 6.05x10⁴s⁻¹
ν = 4955m
In nm:
4955m * (1x10⁹nm / 1m) =
<h3>4.955x10¹²nm</h3>

Answer:</h3>
3CaCl₂ + 2Na₃PO₄→ Ca₃(PO₄)₂ + 6NaCl
<h3>
Explanation:</h3>
We are given the Equation;
CaCl₂ + Na₃PO₄→ Ca₃(PO₄)₂ + NaCl
Assuming the question requires us to balance the equation;
- A balanced chemical equation is one that has equal number of atoms of each element on both sides of the equation.
- Balancing chemical equations ensures that they obey the law of conservation of mass in chemical equations.
- According to the law of conservation of mass in chemical equation, the mass of the reactants should always be equal to the mass of the products.
- Balancing chemical equations involves putting appropriate coefficients on the reactants and products.
In this case;
- To balance the equation we are going to put the coefficients 3, 2, 1, and 6.
- Therefore; the balanced equation will be;
3CaCl₂ + 2Na₃PO₄→ Ca₃(PO₄)₂ + 6NaCl
Answer:
The interaction among organisms within or between overlapping niches can be characterized into five types of relationships: competition, predation, commensalism, mutualism and parasitism.
